Abstract :
Melt spinning was used to produce homogeneous, melt-spun ribbons of Yb1Ba2Cu3 and Yb1Ba2 Cu3 plus various amounts of Ag. While none of these alloys was completely glassy, they did contain glassy alloy and they were homogeneous. Metallic precursors as long as 12 m were produced; the widths were typically 1 to 2 mm, and the thicknesses ranged from 25 to 170 μm. The dimensions of the specimens varied with the alloy composition and the processing conditions
